According to anexemplary embodiment, the bottom wall 406 of the lower rail 400 definesa plurality of apertures (e.g., similar to the attachment apertures320). The plurality of apertures of the bottom wall 406 are configuredto facilitate coupling the lower rail 400, and thereby the seat 40, tothe cabin floor 30 of the vehicle 10.

As shown in FIGS. 6-8 and 13-15, the first sidewall 308 of the upperrail 300 defines a cutout, shown as latch assembly slot 324, positionedbetween the end 302 and the end 304 thereof (e.g., proximate a midpointtherebetween, etc.) and configured to receive a portion of the latchassembly 500. As shown in FIGS. 6-15, (i) the first sidewall 308 of theupper rail 300 defines a first plurality of apertures or slots, shown asretention slots 326, positioned beneath the latch assembly slot 324 and(ii) the first flange 410 of the lower rail 400 defines a secondplurality of apertures or slots, shown as retention slots 426. Accordingto the exemplary embodiment shown in FIGS. 6-15, the upper rail 300defines a first quantity of the retention slots 326 (e.g., between oneand ten slots, between two and eight slots, three slots, four slots,five slots, six slots, etc.) and the lower rail 400 defines a secondquantity of the retention slots 426 (e.g., between two and forty slots,five slots, ten slots, fifteen slots, twenty slots, twenty-five slots,thirty slots, etc.) where the first quantity is less than the secondquantity. According to an exemplary embodiment, the retention slots 326of the upper rail 300 are configured to slidably align with at least asubset of the retention slots 426 of the lower rail 400. As described ingreater detail herein, when the position of the upper rail 300 is in adesired position along the lower rail 400 and when the retention slots326 align with a subset of the retention slots 426, the latch assembly500 is configured to engage with the retention slots 326 and the subsetof the retention slots 426 to facilitate securing the upper rail 300 inthe desired position and prevent relative movement between the upperrail 300 and the lower rail 400.

As shown in FIGS. 6-15, the latch assembly 500 includes (i) an actuator,shown as lever arm 502, and (ii) a locking fixture, shown as latch plate504, coupled to the lever arm 502 with a pin, shown as latch pivot pin510. As shown in FIGS. 6-15, the latch plate 504 includes a pair ofconnectors, shown as latch plate arms 506, that extend from the latchplate 504, through the latch assembly slot 324, and engage with thelatch pivot pin 510 to couple the latch plate 504 to the lever arm 502.In one embodiment, the lever arm 502 is an extension of one of the latchplate arms 506. As shown in FIGS. 6,8, and 10-15, the latch plate 504includes a plurality of projections, shown as latch teeth 508.

As shown in FIGS. 12 and 15, the first sidewall 308 of the upper rail300 includes a pair of supports, shown as latch flanges 328, positionedat opposing ends of the latch assembly slot 324 and extending outwardfrom the first sidewall 308 of the upper rail 300. As shown in FIG. 12,the latch pivot pin 510 interfaces with the latch flanges 328 topivotally mount the latch assembly 500 to the upper rail 300.Accordingly, manipulation of the lever arm 502 causes the latch plate504 to pivot about the latch pivot pin 510 and relative to the upperrail 300.

As shown in FIGS. 7 and 9-14, the latch assembly 500 includes a biasingelement (e.g., a torsion spring, etc.), shown as latch return spring512. According to an exemplary embodiment, actuating the lever arm 502contracts the latch return spring 512 and pivots the latch plate 504about the latch pivot pin 510 from (i) an engaged or locked position (asshown in FIGS. 6 and 8-15) where relative movement between the upperrail 300 and the lower rail 400 is limited or prevented to (ii) adisengaged or unlocked position where relative movement between theupper rail 300 and the lower rail 400 is permitted (e.g., when the latchteeth 508 are disengaged from at least one of the retention slots 326).When the lever arm 502 is released, the latch return spring 512 isconfigured to bias the latch plate 504 to pivot about the latch pivotpin 510 back to the engaged or locked position. While the latch assembly500 is shown as including a manual actuator, in other embodiments, thelatch assembly 500 additionally or alternatively includes anelectronically-controllable actuator (e.g., a motor, a pneumaticactuator driven by an electronic pump, etc.) positioned to pivot thelatch plate 504 about the latch pivot pin 510.

As shown in FIGS. 6 and 8-15, the latch teeth 508 of the latch plate 504extend through the retention slots 326 of the upper rail 300 and asubset of the retention slots 426 of the lower rail 400 when the latchplate 504 is in the engaged or locked position to substantially fix thepositions of the upper rail 300 and the lower rail 400 relative to eachother and prevent movement therebetween. However, as shown in FIGS. 8and 15, the latch teeth 508 are sized or shaped (e.g., undersized,tapered, etc.) such that there is a clearance gap between the lateraledges of the latch teeth 508 and the sides of the retention slots 326 ofthe upper rail 300 when the latch teeth 508 engage with the retentionslots 326. For example, a longitudinal width of each of the retentionslots 326 (e.g., a width of the slots extending between the end 302 andthe end 304) is greater than or equal to a corresponding longitudinalwidth of each of the latch teeth 508. As another example, a shape ofeach latch teeth 508 (e.g., a tapered shape) creates a gap between eachof the latch teeth 508 and each of the retention slots 326. Suchclearance gaps can cause looseness in the track assembly 200, which canallow minor movement between the latch assembly 500 and the upper rail300 (e.g., under loading conditions, during baking, during acceleration,etc.) and cause wear or noise, which is commonly referred to as “chuck.”

As shown in FIGS. 6, 8, and 11-15, the latch assembly 500 includes ananti-chuck mechanism or component (e.g., an anti-chuck plate having oneor more anti-chuck or spring teeth), shown as anti-chuck leaf spring520, coupled to the latch plate 504 with a fastener, shown as rivet 524,to eliminate the “chuck.” In another embodiment, another type offastener is used (e.g., a bolt, etc.). As shown in FIGS. 6 and 8, theanti-chuck leaf spring 520 has a pair of projections or anti-chuckteeth, shown as spring teeth 522. As shown in FIG. 14, the anti-chuckleaf spring 520 includes a single spring tooth 522. In otherembodiments, the anti-chuck leaf spring 520 includes more than twospring teeth 522 (e.g., three, four, five, six, up to the same number asthe number of latch teeth 508, etc.).

As shown in FIGS. 6, 8, and 11-15, the anti-chuck leaf spring 520 andthe spring teeth 522 extend along the latch plate 504 and the latchteeth 508 (e.g., along an exterior face or surface thereof). Each toothof the spring teeth 522 is configured (e.g., positioned, shaped, sized,etc.) to engage with one or both of the sides of a respective one of theretention slots 326 of the upper rail 300 associated therewith when thelatch plate 504 is in the engaged or locked position. According to theexemplary embodiment shown in FIG. 8, each of the spring teeth 522extends laterally past/beyond at least one edge of a respective one ofthe latch teeth 508 that is associated therewith to engage with at leastone of the sides of a respective one of the retention slots 326.Specifically, as shown in FIG. 8, (i) a first spring tooth 522 extendspast a first edge of a first latch tooth 508 of the latch plate 504 anddoes not extend past an opposing second edge of the first latch tooth508 and (ii) a second spring tooth 522 extends past the opposing secondedge of a second latch tooth 508 and does not extend past the first edgeof the second latch tooth 508, and the first spring tooth 522 and thesecond spring tooth 522 are not positioned along adjacent latch teeth508, but at least one latch tooth 508 is positioned therebetween.According to the exemplary embodiment shown in FIG. 15, the spring tooth522 extends laterally past/beyond both edges of a respective one of thelatch teeth 508 that is associated therewith to engage with both sidesof a respective one of the retention slots 326. Such engagement betweenthe retention slots 326 and the spring teeth 522 under the spring loadof the latch return spring 512 causes each of the spring teeth 522 todeflect or otherwise deform and close one or more of the clearance gaps,providing an anti-chuck function to eliminate the “chuck.” According tothe exemplary embodiment shown in FIGS. 11-13, the spring teeth 522deflect and engage with the retention slots 326 of the upper rail 300while still permitting the latch teeth 508 to fully extend through theretention slots 426 of the lower rail 400.

In one embodiment, the anti-chuck leaf spring 520 is manufactured fromspring steel. In another embodiment, the anti-chuck leaf spring 520 ismanufactured from a plastic material. In still another embodiment, theanti-chuck leaf spring 520 is manufactured from an at least partiallycompliant, pliable, malleable, or deformable material that can deflector otherwise deform to provide the anti-chuck function described herein.
